Hola Emanuel,

you can use both in this case, but we prefer "vestir":

Vestir is used when we mean "to dress" more than "getting dressed". Vestirse is used when we are referring to the "process of getting dressed".

If we want to say that someone "dresses" in a certain way/style, with an adverb, we use "vestir", like in these examples:

Vestir is also used, although more formally, as a synomym of "to wear". For example:

I hope this helped.
